a) Domain of the function 0 ≤ d ≤ 21 (0,21)

Range of the function 0 ≤ B ≤ 400 (0,400)

b) Estimate to the nearest hundreds for B(0) is 200

c) Ebony's bank balance first reached $0 on day 12 can be shown as functional notation as - we can add the number 12 below the first point reaching the horizontal axis.

d) Ebony's bank balance remained $0 from day 12 through day 15. The segment which represents the information is - segment 4.

(a) Domain: the collection of values used as input or arguments for the function.

Range: Either the codomain or the function's image is mentioned.

For three weeks, Ebony's bank account was active (21 days). then the domain is 0 ≤ d ≤ 21 (here 'd' refers to day)

Her highest balance was $400 and her lowest was zero, so the range is  0 ≤ B ≤ 400. (Here, 'B' refers to Balance)

(b) When d = 0, the graph's highest point, which represents her highest balance of $400, is displayed. This means that on the first day, the point will probably only be half as high as the highest point. Therefore, we may calculate the nearest hundred for B(0) is about equal to 0.5 * 400 = 200.

(c) In other words, the line of the function first touches the horizontal axis at d = 12; the balance first reached $0 on day 12. Below the first point that reaches the horizontal axis, we can add the number 12.

(d) From day 12 through day 15, the bank balance stayed at zero dollars; this is shown by the vertical axis of segment 4 of graph 4.

COMPLETE QUESTION:

The amount in Ebony's bank account B(d)  is a function of the number of days(d) since she opened the account. The graph shows segments representing her day-by-day bank balance. Although there are no labeled tick marks on the graph, you can answer the questions by using the additional given information as well as your general knowledge of graphs of functions. (Score for Question 1;_ of 4 points) 1. Ebony kept her bank account open for only 3 weeks, and the graph shows the entire 3 weeks. During that time, her greatest balance was $400.

(a) Give the domain and range of the function. 0 ≤ d ≤ 21  domain; 0 ≤ B ≤ 400  

(b) Give an estimate to the nearest hundreds for B(0). Explain how you determined your estimate and tell what B(0) means in the context of the situation.

(c) Ebony's bank balance first reached $0 on Day 12. How would you show that information in function notation? B(12) = 0  

(d) Ebony's bank balance remained at $0 from Day 12 through Day 15. As you count segments from the left, which segment on the graph1, 2, 3, 4, 5, or 6 represents that information? Explain how you know. 4th segment

The larger of the two consecutive numbers is 57

What is a consecutive number?

Numbers that follow one another sequentially are known as consecutive numbers. Every time there are two numbers, there is a difference of 1 between them. If n is a number, then examples of consecutive numbers would be n, n+1, and n+2.  and 1, 2, 3, 4, 5, and so on.

From the question,

Let's say the smaller integer is x

Then the larger integer will be (x + 1)

According to the question,

4 times the smaller = 4x

3 times the larger = 3(x + 1)

⇒ 4x = 3(x + 1) + 53

⇒ 4x - 3x = 56

⇒ x = 56

(x + 1) = 57

Therefore, the larger of the two consecutive numbers is 57

If f(t) be the outside temperature t hours after 12 PM, then the meaning of f(1)>f(7) is the outside temperature 1 hours after 12 PM is greater than outside temperature 7 hours after 12 PM.

The function f(t) be the outside temperature t hours after 12 PM

Therefore,

f(1) be the outside temperature 1 hours after 12 PM.

f(7) be the outside temperature 7 hours after 12 PM.

Then,

f(1)>f(7) is the outside temperature 1 hours after 12 PM is greater than outside temperature 7 hours after 12 PM.

Hence, if f(t) be the outside temperature t hours after 12 PM, then the meaning of f(1)>f(7) is the outside temperature 1 hours after 12 PM is greater than outside temperature 7 hours after 12 PM.

The scale factor of model to the tower is 3:1640.

The scale factor states the scale by which a figure is bigger or smaller than the original figure.

In other words, scale factor is a ratio between two corresponding sides of similar figures.

Therefore, the actual tower is 1,083 feet tall and 410 feet wide at the base.

The scale model currently has a base that is 0.75 feet wide.

Therefore, the scale factor of the model can be calculated as follows;

The scale factor can be written as a ratio or fraction.

The scale factor of the base to the model is the same with the height of the tower to the model.

0.75 : 410

multiply both side by 100

75 : 41000

divide both sides by 25

Therefore,

Step-by-step explanation:

Trust me, this is the right answer.

Answer:

Rate of change =$43

Step-by-step explanation:

Rate of change is also known as the gradient or slope

Gradient= y2 - y1 / x2 - x1

The Xcoordinate is usually written first.

Y2 = 384

Y1= 169

X2=8

X1= 3

Rate of change= 384- 169 /8-3

= 215/5

The value of F(8) is 26.

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The collection of values that could result in a function's outputs is known as the co-domain.

Given:

F (x) =3x+2

Now, F(8)= 3x+2

=3(8) +2

=24 +2

=26

Hence, the value of F(8) is 26.

Answer:it is 32 peices d

Step-by-step explanation:

The number of miles that both the green car and the blue car have to drive to cost the same amount is equal to 28.5 miles.

The number of miles both cars have to travel to cost the same amount can be determined using an algebraic expression. An algebraic expression can be defined as a mathematical equation consisting of both letters and numbers.

As the green car (gc) cost $15 plus $0.50 per mile and the blue car (bc) costs $25 plus $0.15 per mile, an algebraic expression for this problem can be given as follows;

15 + 0.50(x) = 25 + 0.15(x)

Solving for x;

0.50x - 0.15x = 25 - 15

0.35x = 10

x = 10 / 0.35

x = 28.5

Hence, both cars have to drive 28.5 miles to cost the same amount.

The dollar cost y and the amount of yogurt are proportionate

The formula is y = 0.08x

If y fluctuates as directly as x, you may express it as y = kx.

Where k is the proportionality constant.

 Determine the value of the proportionality constant. When y = 2.56 and x = 32, you get:

y = kx

k = y/x

k = 2.56/32

k = 0.08

 The equation is then: y = 0.08

 Check to see if they are directly proportionate. Substitute the amount of yogurt purchased by Jonah. The outcome must be $0,48:
